ABB F204 A-25/0.03 residual current circuit breaker, a 4 pole Type A RCCB with 25 A rated current and 30 mA residual current sensitivity for electrical distribution and protection applications.
The ABB F204 A-25/0.03 is a dependable 4-pole residual current circuit breaker (RCCB) designed to provide reliable protection against earth leakage faults in residential, commercial and industrial electrical installations. As part of the proven ABB F200 series, it helps protect people and installations by disconnecting the circuit when residual current exceeds the rated threshold.
This RCCB is designed for DIN rail installation within distribution boards, switchgear assemblies and control panels. Its Type A operating characteristic detects both sinusoidal alternating residual currents and pulsating direct residual currents, making it suitable for modern electrical circuits with electronic equipment and power conversion devices.
With a 25 A rated current and 30 mA rated residual current, the ABB F204 A-25/0.03 provides additional protection against electric shock while supporting safe and reliable operation in three-phase and neutral circuits.
Residual current circuit breakers continuously monitor the balance of current flowing through live conductors and disconnect the supply when leakage current to earth exceeds the specified threshold. This helps reduce the risk of electric shock and supports safer electrical system operation.
The ABB F204 A-25/0.03 provides Type A residual current protection, making it suitable for installations where electronic equipment may produce pulsating direct residual currents. Its compact construction, DIN rail format and ABB build quality make it a trusted choice for professional electrical installations.
